Självgraviterande

Självgraviterande refers to a hypothetical concept where an object or system possesses enough mass that its own gravitational pull becomes the dominant force shaping its structure. In astrophysics, this concept is fundamental to the formation of celestial bodies. For instance, a collapsing cloud of gas and dust in space begins to self-gravitate, drawing material inward and eventually leading to the formation of stars, planets, or other astronomical objects. The balance between gravity and internal pressure, such as thermal pressure in a gas cloud, determines the stability and ultimate fate of such a system. A sufficiently massive object will overcome internal pressures, leading to gravitational collapse. This principle is also relevant in theoretical discussions about the formation of galaxies and larger cosmic structures. The term implies an internal mechanism driving a cohesive force, rather than an external influence. The concept is a cornerstone of understanding how matter aggregates in the universe.
